There are many greenhouse gases in our atmosphere besides CO2 which contribute to the greenhouse effect that keeps our Earth warm. In addition, many of these gases undergo reactions in the atmosphere, especially when photolyzed by sunlight. One such example is the collection of gases nicknamed “NOx”, which refers to nitrogen oxide (NO) and nitrogen dioxide (NO2). NOx is notorious for the production of ozone (O3) in the troposphere (where ozone contributes to air pollution) and the loss of ozone in the stratosphere (such as the ozone hole in Antarctica that allows harmful UV rays to penetrate to the surface). Imagine you are an environmental chemist trying to better understand the loss of ozone due to the presence of NOx – even in small quantities – in the stratosphere. You set up an experiment in which you have two flasks separated by a valve. Each flask has a pressure of 10 millibar (or 7.50 mmHg) and a temperature of -35.0°C, mimicking the conditions in the middle of the stratosphere. One flask contains 0.0200 grams of nitrogen oxide. The second flask contains ozone and has a volume of 3.00 L. You open the valve and allow the gases to react, creating nitrogen dioxide and oxygen gas. a. Write the balanced equation for this reaction. All reactants and products are in the gas phase. b. After the reaction has gone to completion, what is the total pressure inside your two-flask apparatus?
Atmospheric Pollution
In the atmosphere, the existence of large quantities of undesirable substances that could cause several health issues to living organisms and humans is atmospheric pollution. Air pollution is otherwise known to be atmospheric pollution. The presence of undesirable materials would also destruct the natural environment such as a change in climate, degradation of habitat, or depletion of ozone. Air pollution is generated by the natural processes and activities of humans.
Smokestack Scrubbers
Once we believe in the environment and remember the pollution-producing facets of it, we will consider the smoke-stacks scrubber to be a number of the worst offenders. Although this is often legally correct, smoke-stack scrubbers often have a big function in terms of keeping ground-level air pollutants- safe to breathe and assisting within the management of emissions.
